Wheels Of the Cycle Give Me Power…

Power to juice up my gadgets, power to spike up my laptop! The idea behind re:energy concept is this: you ride the cycle and the wheels function as a generator to convert kinetic energy to power, and store the juice. When you run out of battery for your gadgets, recharge them by hooking them up to this unique cycle. A very do-able idea so you tech-specialists should have fun talking about this…on similar lines, we do have a pedal-driven washing machine invented! Designers: Jinsik Kim and Boseung Seo

Make it so that the loading can be happening during the time you cycle and you might have a winner. Most people will not stay with their bikes when they are done biking. Sol loading during the ride would make more sense.

Because what we need, are bikes which are heavier, bikes which are more expensive, bikes which have devices that actively brake you, making them harder to pedal.

There ain't no such thing as a free lunch: if you generate energy from the turning of the wheels, this means the bike gets harder to pedal, unless you only collect energy while braking, offcourse.

And the collected energy, like always, is somewhere between nonexistant and laughable.

Use your current bike *one* time more each year, rather than drive, and the energy-savings are a hundred times greater than anything this can provide.

There are generators for bikes already, and there have been for decades. Guess what, they're used *less* now than 2 decades ago, people opt to use batteries instead, to power energy-efficient lead-lights. Because the generators, are a drag. And if there's one thing that -doesn't- make it fun to bike, it is adding extra drag.

What these two so called designers actually have done apart from making rendering images? It’s not about the issue that how much extra effort he/she actually need to make to generate energy. It’s about the incentive for people to use this “Green” product and the user scenario, even user interface. I reckon these designers need to make a working prototype first. And then see if themselves would bother to charge gadgets when stopping, as well as people around. Then we can talk about the feasibility. Please do something outside of computers.

That's right: DYNAMOS in kids' bikes have been around for at least 50 years. This design has the entire thing in the wrong place. I recommend something simpler a kid could put together: Get a high-efficiency bike, dynamo, and rechargeable batteries (to compensate for the increased work and battery weight inevitably required by this concept) and throw it all into the frame (see i-cycle) and bike harder! Knowing you are burning more calories while recharging your gadgets on-the-fly (and not sitting on some bench around the dirty wheels of your bike!) should satisfy your inner tree-hugger. Oh, and get rid of the recycle symbol! It'll keep you from looking as though you are riding a couple of bin lids.

Can realistically be done. Take the standard coil kinetic idea. Add a secondard rim that is the coil and have a free moving spherical harvest mechanism that is in a constant state of motion based on the turning action of the pedaling. Essentially a constantly moving “shake to charge” flashlight. Energy transfer and long term storage for such a device would be difficult. But given you can run a shake flashlight for 5mins off 5mins of shaking, you could realistically expect more efficiency based on far better kinetics of a weighted coil in constant kinetic motion. Transferring and storing such amounts of energy would require R&D..
